The real question here is, since CBC content is funded by the public, shouldn’t the public own it? Or at least have access to it? Actually, the CBC archives are just the tip of the iceberg: the overwhelming majority of stuff made for Canadians with Canadians’ money is inaccessible to Canadians.
In Canada, movies are supported by Telefilm, TV by the Canadian Television Fund, books and art by The Canada Council for the Arts, and so on. But most of this stuff isn’t distributed very well or for very long, and you can only get your hands on a fraction of it.
So I want to put forth one more contrarian position: I think that any publicly funded content should (within, say, 5 years of its creation) be released to the public domain.
